A substance with a pH of 6 is considered slightly acidic. The pH scale, which measures the concentration of hydrogen ions, ranges from 0 to 14 where a pH of 7 is neutral. A substance with a pH below 7 is acidic, while a substance with a pH above 7 is considered basic or alkaline.
A substance with a pH of 6 is often considered slightly acidic. The pH scale measures the concentration of hydrogen ions (H+) in a substance and ranges from 0 to 14 where a pH of 7 is considered neutral. Anything below 7 indicates an acidic solution, and anything above 7 is considered basic or alkaline. So, a substance with a pH of 6 is closer to the neutral point, but is still acidic as it falls below 7. Since one unit on the pH scale represents a decrease in hydrogen ion concentration by a factor of 10, a solution with a pH of 6 is 10 times less acidic than one with a pH of 5, but 10 times more acidic than a neutral solution at pH 7.

Decomposers
Primary consumers
Secondary producers
Answer: Primary producers
A food chain is a linear series of transfer of food and energy when one organism is consumed by the other organism in an ecosystem. The energy is distributed among different tropic levels of the food chains.
Phytoplankton is a class of unicellular simple, autotrophic organisms which are found in water of ocean, lakes and or any other freshwater body. These includes dinoflagellates, diatoms, cynobacteria, green algae and others. These organisms are abundantly present in the ecosystem in the lower most trophic level. They are called as primary producers because they are consumed by other organisms such as zooplanktons, fishes and large sea mammals.
